The exclusive decay B-->K^* mu mu has gained a lot of attention because the recent LHCb angular analysis has indicated significant deviations from the Standard Model which could be interpreted as a possible first signal of new physics. The sensitivity of theory predictions to hadronic input parameters can be minimized be choosing an optimized set of observables. On the other hand, non-perturbative Lambda_QCD/mb power corrections introduce a source of uncertainty for theory predictions as they cannot be calculated from first principles. In my talk I will present a systematic approach to estimate factorizable power corrections and discuss their impact on angular observables.
